Abstract
Nuclear microprobe analysis (NMA) was used to study lithium and boron stability and distribution in minerals and synthetic glasses. Beam cur rent densities up to 20 pA/muM2 for deuterons and less than 25 pA/mum2 for protons do not alter the composition of the studied materials. Ph yllosilicates, pyroxenes, glasses and tourmalines were quantitatively characterized and found to exhibit a certain degree of depth inhomogen eity. The analytical capabilities for lithium and boron isotopic ratio measurements by NMA are then discussed.
